Ahmed Bougacha 3c9fb6e1ad [AArch64] Improve codegen of store lane instructions by avoiding GPR usage.
We used to generate code similar to:

  umov.b        w8, v0[2]
  strb  w8, [x0, x1]

because the STR*ro* patterns were preferred to ST1*.
Instead, we can avoid going through GPRs, and generate:

  add   x8, x0, x1
  st1.b { v0 }[2], [x8]

This patch increases the ST1* AddedComplexity to achieve that.
